This article presents e-PWV, a web application for the determination of Pulse Wave Velocity (PWV) running on a web platform called NooLib. e-PWV has been applied on signals recorded by an ultrasound system (PWVet, Aloka, Japan) and representing the arterial diameter changes in carotid and femoral sites. PWVetmeasurements were compared to PWV recorded by a tonometric technique (PWVpp, PulsePen, Italy). The study was conducted on 120 patients. We found an excellent correlation of r = 0.95 between PWVetet PWVpp(P< 0.0001; 95% confidence interval of 0.91â0.96; PWVet= 0.88 Ã PWVpp+ 0.57). We observed a small offset of - 0.33 ms- 1on the Bland-Altman plot with a limit of agreement from - 2.21 to 1.54 ms- 1. Our results suggest that e-PWV application can produce online a reliable marker of the regional aortic stiffness using an echotracking system.

Abstract
This article presents e-PWV, a web application for the determination of Pulse Wave Velocity (PWV) running on a web platform called NooLib. e-PWV has been applied on signals recorded by an ultrasound system (PWVet, Aloka, Japan) and representing the arterial diameter changes in carotid and femoral sites. PWVetmeasurements were compared to PWV recorded by a tonometric technique (PWVpp, PulsePen, Italy). The study was conducted on 120 patients. We found an excellent correlation of r = 0.95 between PWVetet PWVpp(P< 0.0001; 95% confidence interval of 0.91â0.96; PWVet= 0.88 Ã PWVpp+ 0.57). We observed a small offset of - 0.33 ms- 1on the Bland-Altman plot with a limit of agreement from - 2.21 to 1.54 ms- 1. Our results suggest that e-PWV application can produce online a reliable marker of the regional aortic stiffness using an echotracking system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
